Part Number: UCC2897A
Other Parts Discussed in Thread: PMP5123

Dear Team,

Customer was studying UCC2897A for

Vin:10~53V

Vo:8V

Io:9A

Because UCC2897A's minimum Vin is 18V.

Do you have a suitable controller that can work from 10~53V?

If you have a suitable reference design is appreciated!

Hi Kevin,

We have some reference designs with UCC2897A below 18V input. The biasing issue was addressed by using a switched capacitor circuit to boost up the voltage going to the VIN pin. Please share with your customer PMP5123 as an example:https://www.ti.com/tool/PMP5123
